According to the chemical equation: 3AB + c2b3 = 2C + 3x, the chemical formula of X is determined as () A. AB2B. A3B2C. A2B3D. AB3

According to the chemical equation: 3AB + c2b3 = 2C + 3x, the chemical formula of X is determined as () A. AB2B. A3B2C. A2B3D. AB3

In the reaction 3AB + c2b3 = 2C + 3x, according to the law of conservation of mass, before and after the reaction, the type of elements, the type of atoms and the number of atoms remain unchanged, while the C atom is equal before and after the reaction. If there are three a atoms and six B atoms before the reaction, then there should be three a atoms and six B atoms after the reaction, then there are three a atoms and six B atoms in X, and the stoichiometric number of X is 3, then the chemical formula of X is AB2, so a is selected
